To' all whom it may concern:

lllc it known that l, ROBERT Szozs, a. citizen o the United States,residing;r at Minto, in 'the county oi Walsh and State el NorthDa'kota,' have invented cer tainvnew and useful Improvements inDisplay-Racks; andi do hereby declare the following to be a. full,clear, and exact descriptioniof the invention, such as will enableothers skilled in the art to which it appertains to make and use thesaine.

This invention has for its object to provide an irnproved display rack,by means or' which various articles of merchandisemaybe displayed inysucceeson, either iordadvertising purposes or for convenience in makingsales, or hoth. l "il devices and combinations `or' devices hereinafterdescribed and defined in the claims.y

Ilitherto in display racks a series of shelves haveY been hung oriendless chains or traveling conveyors,

i and have received movements theririrom todispla-y articles ol'merchandise in succession, hut in these prior devices .the suspendedshelvesl have not been posi tively heldagltirist vibration or swingingmovernents, and Vit has been found `that they would `vibrate. or swingto a` very considerable extent, especially in niakingthe turnsat `theupper and lower portions of thc conveyor or endless carrier.l i

The principal feature of my present `invention is direct-id 'to theprovision ol' simple andefiicient means` for positively`preventingvibrations on swinging 1nove ments of the shelves atal times throughout`their `comlplete travel.

The iin'provcd device embodying the above notedv feature oi improvementand other features hereinafter" noted or einhodiml intheiniprovedmachinelillustinted in the accompanying drawings.

in the drawings like (`:haracterls rindicate like parts throughout theseveral views., i l l Referring to the drawings, Figure l is e 'viewpartly in elevation .and partly insection on theline rb c' of Fig. 2,.showing a `cabinet or ease and "illustratinbr my inventionapnlcdmthereto. Fig. 2 is a transverse vertical section taken enk theline z2 a o i Fig'. 1. Fig. 3 is a detail view, in elevation showing oneof the shelves removed iromworking position. Fig. 4 is aplan view of theshell' shown in Fig. 3. Fig. 5 isa transverse section taken on the lirie2:5 :rl oi Fig, 4, some .parte be` ing Vbroken away, and Fig. 6 is viewprincipally in elevation but with some parts sectioned and with some,arts broken-away, showings form of the device' in Vwhich the cabinet orcase is extendedthrough lseveral stories of a building. Y

Referring first to the construction illustrated `in Figs.

l to 5 inclusveftlie uumeml 1 indicetesan uprights ings 6, on the sidesthereof a` considerable distance above the bottom of the cabinet, is atransverse shaft 7 that carries u pair of laterally spaced sprockets 8,which sprockets aline one with each. o the sprockets 5. The sprocketchains 9.run over the alined sprockets 5 and 8. Mounted in bearings l()located on the sides ofthe cabinet l directly below the bearings 4, butTo the above end the invention consists oithe novel laterally offsetinward therefrom, is a pair of sprockets l1; A'lhcse sproeketsll arealincd one with each o it pair of Sprockets l2, which latter are mountedon the depending ends of quite long and thin braekfks 13,

the upper ends of which' are attached to the sides o f i the cabinetabove the sprockets 8i Sprocket eli-.tins Mvrun over the slned sprockets1l and l2. The

axes o the sprocketsi and 8 :ire in the suine vertical plane, and thevertical distance hetweentlu axes ofthe sprockets ll and l2 is thesinne, as the vertical distance` between the axes o1' tlwsproekets 5 and8;

hence itol' course follows that the vertical distance he tween the axesof the upper sprockets `fl mull1l`is the saine as the vertical distancebetween the axes 'of the lower sprockets 8 and l2. Thislielv\ l5 armynsshown, provided at their ends"witl1 he: 'iner hubs lo ythat areadjustahl-y secured liyset-sm'exvs 17 to the lower ends oi supportinglinks J8, the,.l1.nver ends `oi which links are turned linward and the,Upper ends nl iwlliih are turned outward# The `chains Dure liro videdat the proper intervals ol' space with links that have perorated hearinglugs 19, and4 likewise the chains vl-l at corresponding iuervnls ol`space, hut have i verticallyolf-set points. are provided with links that11 and between the aires of `the sprockets and 12..

lhe bearing brackets 13, it lie-noted, ,are attached ie the sides of thecubinetat'points above the shaft',

and are oflsct laterally froml the planes of tra-vel of'the '165 links18, so 'that the' linke in making theirlower transverse movements passclear of said brackets. With this arrangement when thegsprockctquippedshalt 7 is rotated all o the sprockets will be caused to rotate inunison, the chains will be caused to travel parallel courses, and thelinks 18 tlnoughout their movements will be held in vertical position.lt therei fore follows that it' the shelves l5 oe sot in horizontal'throughout their movements.

position they will maintain such horizontal position l the shelves beset in an oblique position they will be hold parallel to that '.positionthroughout their movements. The two pairs of chains hold the 18 andhence the shelves supported thereby against vibrations or swingingmovements, throughoutufthe entire line of travel thereof.

l outward below the shelves.'` (Sec Figs.

To adapt the shelves tosupport articles such as hats, they are providedwith longitudinal slots l8r', and skeleton spring holders 29ers mountedfor sliding movements in said slots. These holders 29 are, as shown,formed by intersecting bowed springs, the ends o'which are passedthrough said slots and. are turned 3, 4 and 5.) In Fig. 2 one oftheshelves is shownas set in an'oblique position, as may be required forproperly displaying a great many kinds. of merchandise. Asa Vmeans fordriving the chains by han d power l. have shown a crank 22 mounted inand extending `through one side' o the cabinet, and having at its innerend a pinion 23 that meshes directly lwith one'oi the lower sprockets 8.When the chains are to be driven from another source ol power, theshaft' 22 maybe 4provided at its outer end with apulley orsprocket, oranyother suitable means may be provided ortransmitting the .motion 'tosaid sprockets und chains. l

In Fig. 6 the numeral 24 indicates' the floors of difierent stories inthe building, and in this arrangement the cabinet 1 isextended from whatmaybe assumed to be the, basemnt, throughy the first story and into thesecond story. The upper 'portion o the cabi-net is in the form of aglass showcase 25.r in the basement and in the 'first loor sectionthecabinet is shown as provided with hinged glass 'doorsv 26, and abovesaid doors with glass windows27. The: upper sprockets 5 andll` aremounted within the showcase section 5,- and the lower sprockets 8 and 12v',tijelocated in thebasernent section of the cabinet near the basementfloor. The sprocket shaft 7 is.shown-"as extended and provided with apulley 28, ovgijwhich a power-driven bltlnot shown) may run ti'ii'impartmotion to the sprocketsv mil chains. The sprocket chains, are. oicourse, lengthcned out to correspond to the increased length oi thecabinet.

For advertising purposes means would bc usually provided for impartingcontinuous motion io the sprockets and chains, and the transparentsections ol' the cabinet would 0i course be disposed wherel they wouldbest display the articles oi merchandise carried by the shelves. Wherethe device is used for the purpose ol exhibiting goods ,in making sales,means would usually be provided for imparting intermittent niovements tothe chains,` or for moving the saine at will, as

and put into actu-.il use, and it has been found cllicientl ior thepurposes had in view.

What l clairn is:

1. In a device of the kind described, the combination with the uppersprockets 5 und the upper sprockets 11, said latter being off-setlaterally and vertically below the former, of the lower sprockets `8 and12 the former bc'iug alined vertically with said sprockets 5, and thelatter with said sprockets 11, the distance betweensaid sprockets 5 and8 being the same as the distance between said sprockets 11 and 12,brackets 13 supporting said sprockets 12 at their lower endsandthemselves supported at' their upperrcnds above said sprockets8,-.sprocket chains '9 running over the sprockets 5 and 8, sprocketchains 14 running over the sprockets 11 dhd12, crank-llke-links 18pvotally con- 'nected to links of said chains 9 and 14, and shelves 154adjustably secured to the lnturned ends of'sad links 13,

;substantlally as described.

2. In a device of the kind described, the combination with an endlesscarrier, of o. shelf attached to said cari-ler, said shelf having alongitudinal slt. and a skeleton holder mounted to slide in sa'ld'scrlbcd.

In testimony whereof I affix my signature in presence of two witnesses.
